Negative prompt specifying image details to exclude, including colors, objects, scenery, or finer features. Examples include a moustache, blur, or low resolution.

default 3

Duration in seconds to animate, starting at the beginning of the video.

default 25

Count of inference steps to run.

default 0.7

Degree of influence the input video has on the final result.

default 7.5

Prompt-adherence strength for image selection, expressed as CFG (Classifier Free Guidance).

default 8

Frame extraction rate from the video, in frames per second.

Seed for reproducing images in Stable Diffusion. An image can be reproduced exactly on every run by keeping the model version, prompt, and seed unchanged.

Motions applied to the video.

About AnimateDiff · Video to Video

Re-animates `video_url` according to a `prompt`, using only the first `first_n_seconds` (2 to 4, default 3). `strength` from 0 to 1 sets how much the source video shows through. It also accepts `motions`, `negative_prompt`, `guidance_scale`, `fps` up to 16 and up to 50 inference steps.

Parameters

Send either the canonical name or the native name, not both. Canonical names
